2 is a flowchart of a method of developing and processing RAW data in an imaging device using an external device according to an exemplary embodiment.

As shown in FIG. 2, an external device (not shown) according to an embodiment may include a PC 91. In this case, as shown in FIG. 3, the imaging device 1 and the PC 91 according to the exemplary embodiment may be connected through a USB cable. In addition, the PC 91 according to an embodiment may include a monitor 92 as a display means.

In step 101, the PC 91 starts up an application (software) for setting development parameters according to the user's operation. In this case, when the application is started, the PC 91 can recognize that the imaging device 1 is connected.

In step 102, the PC 91 transmits a notification to the imaging device 1 indicating that the development processing mode is executed.

For example, a notification of the content that development processing is started can be transmitted to the imaging device 1 by the user operating the application.

Further, the PC 91 can transmit a request for acquiring interface information to the imaging device 1 together with a notification of the start of the development process.

It is assumed that the application according to the embodiment is stored in the PC 91 in advance.

For example, the application is a general-purpose application that does not depend on the model of the imaging device, and a developing interface dedicated to the imaging device 1 can be constructed based on the interface information transmitted from the imaging device 1. The developing interface according to an embodiment includes an interface that accepts an operation for setting a developing parameter.

In step 103, when the imaging device 1 receives a notification that the development processing mode is executed from the PC 91, it transmits the interface information previously stored in the memory 10 of the control unit 101 to the PC 91. .

The interface information according to an embodiment may include information for displaying a developing interface on the monitor 92 of the PC 91.

For example, the interface information may include at least one or more of information on a development parameter, content of a control command corresponding to the imaging device 1, and image data used to display a development interface.

For example, information on development parameters includes the type of development parameter, the range (upper and lower limits) that the development parameter can be taken, the initial value of the development parameter, the stride of the development parameter, the unit of the development parameter, and the data of the development parameter. It may include at least one or more of a list of options of quantity and development parameters.

In addition to the interface information, the imaging device 1 can also transmit information about the main body of the imaging device 1 or information about RAW data to be developed to the PC 91.

The information on the main body of the imaging device 1 according to an exemplary embodiment may include information on the specifications of the imaging device 1. For example, the information on the main body of the imaging device 1 is the monitor size (resolution) of the display unit 105 of the imaging device 1, the capacity of the temporary storage unit 108, the model name of the imaging device 1, and the imaging device. (1) may include at least one or more of the types of correction processing that can be processed.

The imaging device 1 according to an embodiment transmits these information so that when the PC 91 transmits various data to the imaging device 1, the PC 91 transmits various data to the specifications of the imaging device 1 Can fit in

Further, the information on the development parameter and the information on the main body of the imaging device 1 may include unique information depending on the manufacturer or model of the imaging device.

The information on RAW data according to an embodiment may be information for specifying RAW data to be developed. For example, the information on RAW data may include at least one of a file name, a data size, and a creation date and time of the RAW data.

In step 104, the PC 91 constructs a developing interface based on the interface information received from the imaging device 1.

For example, the PC 91 can display a development interface including information indicating the types of development parameters usable for the imaging device 1 on the monitor 92 of the PC 91. Accordingly, the user can set (adjust) development parameters using the development interface displayed on the monitor 92.

In step 105, the PC 91 sets development parameters using the development interface based on the user's input.

For example, setting development parameters means not only inputting values of various development parameters using a development interface, but also selecting the type of development parameter to be used, or correction processing to be executed among a plurality of correction processing included in the development processing. It may also include selection of.

When the setting of the developing parameter in the PC 91 is completed in step 105, the PC 91 transmits the set developing parameter to the imaging device 1 in step 106.

In step 107, the imaging device 1 executes a developing process using the image processing unit 104 based on the developing parameter received from the PC 91. Accordingly, development data in a displayable format (for example, YCbCr format) may be generated on the display unit 105.

In step 108, the imaging device 1 displays the developing data generated by the image processing unit 104 on the display unit 105.

For example, the control unit 101 of the imaging device 1 can control to display the developing data generated by the image processing unit 104 on the display unit 105. Accordingly, the user can check whether or not the development data subjected to the development process is an intended image by using the set development parameter. In addition, if the image has an intended image, the image pickup device 1 can store the development result in the recording medium 110 or transmit it to the PC 91 to store it in the recording medium in the PC 91 according to the user's operation.

In addition, the control unit 101 may control the display unit 105 to display a plurality of development data developed by using different development parameters. Accordingly, the user can easily compare the development results of different development parameters.

3 is an overall schematic diagram of a system for performing a developing processing method in an imaging device using an external device according to an exemplary embodiment.

As shown in FIG. 3, the imaging device 1 and the PC 91 according to an exemplary embodiment may be connected through a USB cable. In addition, the PC 91 according to an embodiment may include a monitor 92 as a display means.

4 is a block diagram of an image processing unit 104 of an imaging device according to an exemplary embodiment.

As shown in FIG. 4, the image processing unit 104 may include a RAW processing unit 401, an RGB processing unit 402 and a YC processing unit 403.

For example, image data (RAW data) generated by the imaging unit 103 may be converted into a format of RAW data → RGB data → YC data through each process. In this case, in general, it is impossible to view and display in the state of RAW data, and it is possible to view and display in the format of RGB data or YC data.

The RAW processing unit 401 according to an embodiment performs an operation for each pixel (pixel) of RAW data using a value of a pixel around a pixel to be processed, and performs a complementary process (so-called demosaic processing) of the pixel to be processed. can do. Accordingly, RAW format data is converted into RGB format data. In addition, the RAW processing unit 401 may output the generated RGB data to the RGB processing unit 402. For example, the RGB data may include data including three color values of red, green, and blue in each pixel.

The RGB processing unit 402 according to an embodiment may perform image processing on RGB data and convert it into YC (YCbCr) format data. For example, conversion to YC data can be performed as pre-processing for JPEG compression or MPEG compression. In addition, the RGB processing unit 402 may output the generated YC data to the YC processing unit 403. For example, YC data may include data including luminance information and color difference signals in each pixel.

The YC processing unit 403 according to an embodiment may perform various correction processes such as gamma correction on YC data generated by the RGB processing unit 402. In addition, the YC data corrected by the YC processing unit 403 may be compressed to become JPEG format data.

In addition, during the RAW development process as described above, for example, RGB data is input and RGB processing is performed. In this step, the RAW data is not processed, but for simplicity, all or part of these processes are described below. Is collectively referred to as “development treatment”. In particular, individual expressions such as RGB processing and YC processing are performed only when you want to specify and emphasize the processing. Since dedicated hardware (processing circuit) for developing processing is mounted in the image processing unit 104 of the imaging device 1, the developing processing can be completed in a short time.

Further, in each process, a more detailed process is performed. For example, in the RAW processing unit, a demosaic process that converts RAW to RGB is the main process, and various processes such as adjusting the gain of each color or performing noise removal processing as pre-processing are performed. Many development parameters are required for such processing. A simple example of the development parameter is 1-bit data for switching the processing ON/OFF, and a complex example may be data reaching several KB. In addition, since the developing process performed by the image processing unit 104 can use an existing technique, a more detailed description will be omitted.

As described above, according to the configuration of the imaging device 1 according to the present embodiment, the memory 10 of the control unit 101 according to the embodiment can store the type of development parameter and the like as interface information.

Also, the communication unit 107 according to an embodiment may transmit interface information to the PC 91. Also, the communication unit 107 according to an embodiment may receive a development parameter set in the PC 91.

In addition, the image processing unit 104 according to an exemplary embodiment may perform development processing using a development parameter received from the PC 91. Accordingly, setting (adjustment) of developing parameters can be performed on the PC 91 having high operability and visibility. As a result, the user can easily set development parameters.

In addition, the developing process itself according to an exemplary embodiment is performed in the image processing unit 104 of the imaging apparatus 1 provided with dedicated hardware for development, not the PC 91. Therefore, it is possible to realize high-speed development processing.

In addition, the imaging device 1 according to an exemplary embodiment may transmit interface information including a type of development parameter to the PC 91. Therefore, the PC 91 does not need to recognize in advance the types of development parameters that can be set (adjusted) by the imaging device 1.

That is, the PC 91 only needs to have a general-purpose application for setting development parameters, and it is not necessary to have a development parameter setting application specialized for the imaging device 1. Therefore, it is possible to construct a developing interface in the PC 91 without depending on the model of the imaging device.

(Modified Example 1)

Modification Example 1 according to the present embodiment will be described. In the developing process, the developing parameter is changed little by little, and the developing process and the result are repeatedly checked again and again until the user's intended development result is achieved.

For example, after finding an optimal condition for a parameter set in the RAW processing unit 401 of FIG. 4, the RGB processing parameter is changed many times to find the RGB processing parameter. In this situation, it is wasteful to repeat the process of RAW, which has already determined the development parameters.

The imaging device 1 according to Modification Example 1 stores a result during development processing (RGB data resulting from RAW processing in the above example; hereinafter, also referred to as intermediate data) in a DRAM serving as a temporary storage unit 108. Then, the image processing unit 104 acquires the intermediate data from the temporary storage unit 108 and continues the developing process using the changed developing parameter (in the above example, the parameter of RGB processing). This does not repeat the RAW processing, but only the processing after the RGB processing.

Accordingly, it is possible to omit the RAW processing using the same parameters, and thus the efficiency and speed of the development processing can be improved.

Also, the control unit 101 can transmit the intermediate data stored in the temporary storage unit 108 to the PC 91. For example, a case in which the developing application possessed by the PC 91 is more functional and multifunctional than the developing processing of the image processing unit 104 of the imaging device 1 can be considered.

In this case, the imaging device 1 transmits intermediate data to the PC 91 so that only the processes that cannot be performed in the image processing unit 104 can be performed in the PC 91, and other processing can be performed in the imaging device 1. .

(Modified Example 2)

Modification Example 2 according to the present embodiment will be described. After transmitting the developing parameters set in the PC 91 to the imaging device 1, only a part of the developing parameters may be changed. In this case, the developing process is performed again using the changed developing parameter, but the changed developing parameter is a part. Therefore, if all the developing parameters are transmitted every time the developing parameters are changed, the transmission of the unchanged developing parameters becomes wasteful.

When the imaging device 1 according to the modification example 2 acquires only part of the developing parameters from the PC 91, other developing parameters are not acquired again. That is, the developing device 1 stores the developing parameters used in the RAW processing, RGB processing, and YC processing in the temporary storage unit 108. Then, for the developing parameters not acquired from the PC 91, the imaging device 1 refers to the temporary storage unit 108 and reuses the developing parameters previously used for the developing process. Thereby, the PC 91 only needs to transmit a part of the changed developing parameters to the imaging device 1, and it is not necessary to transmit all the developing parameters every time the developing parameters are changed. As a result, it is possible to improve the efficiency of transmission and reception of development parameters.

(Modified Example 3)

Modification Example 3 according to the present embodiment will be described. As for the development process, there is a case where the result of a part of one image is in an intended state (brightness, color tone, sharpness, etc.). For example, if you want to make the color of the sky your favorite blue, or if you want to make a person's face more clear. In this case, it is wasteful to develop the entire image every time the development parameter is changed.

The imaging device 1 according to Modification Example 3 cuts out a part from a single image and performs development processing. Specifically, the imaging device 1 receives the coordinates of an area to be developed among image data (RAW data) from the PC 91 together with a developing parameter. Then, the image processing unit 104 cuts out an area corresponding to the received coordinates from the RAW data, and develops only the cut-out RAW data. Then, the control unit 101 causes the result of the development process (development data) to be displayed on the display unit 105 of the imaging device 1.

The user changes the development parameter again if the area subjected to the development process is not the intended result. On the other hand, if the area subjected to the development process is the intended result, the user instructs the imaging device 1 to develop the entire image using the corresponding development parameter. As described above, a part of the image is cut out and developed, thereby reducing the amount of data in the repeated development process until a user intended development result is achieved. As a result, the developing process can be performed efficiently.

Also, the control unit 101 may display only a part of the development data on the display unit 105. That is, the control unit 101 causes the display unit 105 to display only a portion cut out by the image processing unit 104 and subjected to the development process. As a result, only a part of the image designated by the user is displayed on the display unit 105. Therefore, the user does not need to find the cut-out portion of the entire development data, so that the development result can be easily checked.

(Modified Example 4)

Modification Example 4 according to the present embodiment will be described. The imaging device 1 according to Modified Example 4 can develop RAW data stored in the PC 91 as well as RAW data on the recording medium 110 mounted on the main body of the imaging device 1.

Specifically, the imaging device 1 receives from the PC 91 the development parameters set by the PC 91 using the development interface and RAW data previously stored in the PC 91. Then, the image processing unit 104 develops the received RAW data by using the received development parameter. In this way, even when the processing power of the PC 91 is low to perform the developing process, the developing process itself can be executed by the imaging device 1. That is, the imaging device 1 connected to the PC 91 can be used as a developing device. As a result, the PC 91 can develop the RAW data stored in the PC 91 as long as it has the processing capability to execute the developing interface for setting the developing parameters.

(Modified Example 5)

Modification Example 5 according to the present embodiment will be described. The imaging device 1 according to the fifth modification stores an HTML (Hyper Text Markup Language) file as interface information in the memory 10 of the control unit 101. The interface information is an HTML file, so it can be viewed using a web browser.

Specifically, the memory 10 of the control unit 101 includes the characters of the development interface displayed on the web browser of the PC 91 (for example, characters indicating the type or value of the development parameter), the location of the characters and images. And an HTML file including information on the layout of the entire interface and the like is stored in advance. In addition, the memory 10 of the control unit 101 also stores image data such as icons used for the developing interface. Then, the imaging device 1 transmits the HTML file and necessary image data as interface information to the PC 91.

The PC 91 can display the developing interface on the monitor 92 of the PC 91 by opening the received HTML file using a web browser. That is, in order to display the developing interface, the PC 91 only needs to have a web browser function and does not require a special developing application. Therefore, it is not necessary for the PC 91 to previously have a developing application dedicated to the imaging device. As a result, it is possible to construct a developing interface in the PC 91 without depending on the model of the imaging device.

In addition, by including sentence information for explaining the processing performed by the imaging device 1, a development parameter, and a method of operating a development interface, etc. in the HTML file, the user can deepen understanding and set the development parameter. In addition, a file that can be displayed using a web browser is not limited to HTML format, and may be XHTML (Extensible Hyper Text Markup Language) or XML (Extensible Markup Language).

6 is an overall schematic diagram of a system for performing a developing processing method in an imaging device using an external device according to another exemplary embodiment.

As shown in FIG. 5, the imaging device 2 may further include an external display control unit 201. In addition, since other configurations are the same as those of the imaging device 1, descriptions will be omitted appropriately.

As shown in Fig. 6, the imaging device 2 is connected to the display device 93 via, for example, an HDMI (registered trademark) (High Definition Multimedia Interface) cable. For example, the display device 93 may include a television or a PC monitor, and may have a screen having a size larger than that of the display portion 105 of the imaging device 2.

The external display control unit 201 according to an exemplary embodiment may be connected to a display device external to the imaging device 2 to control display of the corresponding display device.

The external display control unit 201 according to an embodiment transmits the development data developed by the image processing unit 104 to the display device 93 and displays an image corresponding to the development data transmitted to the display device 93. I can. In addition, the adjustment of the development parameter can be performed using the PC 91 and the monitor 92 in the same manner as in FIG. 2.

The external display control unit 201 of the imaging device 2 according to another exemplary embodiment may display an image for which the development process has been completed on an external display device 93 different from the display unit 105 installed in the imaging device 2. Accordingly, the user can check the result of the developing process on a screen larger than the display unit 105. Therefore, visibility can be improved.

In addition, the external display control unit 201 may display an image based on intermediate data during development on the display device 93. For example, by displaying an image of RGB data after RAW processing as an image during development, the user can confirm on a large screen whether the RAW processing has an intended result.

Also, the external display control unit 201 may display only a part of the developed image on the display device 93. In this way, the user can check on a large screen whether or not the developing process of a partial area of the image has an intended result.

In addition, the external display control unit 201 may arrange and display a plurality of development data processed using different development parameters on the screen of the display device 93.

Accordingly, the user can compare development data developed by a plurality of different development parameters on a large screen.
